SDSS spectra of the QSO-LAE lensing systems candidates. Right panels: 5-pixel smoothed BOSS spectra (black) and QSO fitted PCA template (red). The detected extra emission line is indicated by the dashed green line. Left panels: zoom on the original spectra of the candidate lensed Lyman-α emission line. We note the asymmetric profile characteristic of Lyman-α.
